There are always going to be sports at the Winter Olympics that seem foreign to us. For example, I’m pretty sure I’ve never met anyone who does biathlon, and I know for a fact I don’t know any ice dancers.

However, no sport is more mysterious and peculiar to me than curling. Sometimes I just cannot believe that this is an Olympic sport and that it actually plays on my television once every four years. The whole thing is just a complete mystery. I mean yes, I get that you want to get your sliding rocks on the bullseye, but what’s with the sweeping? Does that really make a huge difference?

Anyway, in my book curling is the most unusual event at the Winter Olympics. And I know for a fact that I’m not alone. BBC Radio’s Greg James thinks it’s pretty crazy too, so he managed to convince Sir David Attenborough, the voice of every nature documentary you’ve ever seen, to provide alternative commentary for the women’s curling match between Team GB and Team USA.
